Planning and Documenting an HA Cluster
Package Configuration Planning
Chapter 4182
These array parameters, entered together as triplets
into array variables. Each triplet specifies a filesystem,
a logical volume, and a mount option string for a file
system used by the package. In the package control
script file, these variables are arrays, as follows: LV, FS
and FS_MOUNT_OPT.
On starting the package, the script may activate one or
more storage groups, and it may mount logical volumes
onto file systems. At halt time, the script unmounts the
file systems and deactivates each storage group. All
storage groups must be accessible on each target node
(CVM disk groups must be accessible on all nodes in
the cluster). For each file system (FS), you must
identify a logical volume (LV).
A logical volume can be built on an LVM volume group,
a VERITAS CVM disk group, or a VERITAS VxVM
disk group. LVs can be entered in any order, regardless
of the type of storage group that is used.
Filesystem Unmount Count
The number of unmount attempts allowed for each
filesystem during package shutdown. Default is 1.
Filesystem Mount Retry Count
The number of mount retrys for each filesystem. The
default is 0. During startup, if a mount point is busy
and FS_MOUNT_RETRY_COUNT is 0, package startup will
fail and the script will exit with 1. If a mount point is
busy and FS_MOUNT_RETRY_COUNT is greater than 0, the
script will attempt to kill the user responsible for the
busy mount point for the number of times specified in
FS_MOUNT_RETRY_COUNT. If the mount still fails after
this number of attempts, the script will exit with 1.
CONCURRENT_VGCHANGE_OPERATIONS
Specifies the number of concurrent volume group
activations or deactivations to allow during package
startup or shutdown. The default is 1. Setting this
variable to a higher value may improve performance if
you are using a large number of volume groups. If a
